Am always up for going trail riding in any of the state ATV/ORV trails that are within an hour or two of Midland/Bay City/Saginaw.

If you have a group going, and don't mind a "tag-a-long" or interested in forming a group for a day, please let me know.

Have three quads, 1 enduro bike, two trailers (10ft, and 16ft) and two trucks haul this stuff and usually room to add a bike/quad on either.

Currently, Gladwin and Leota near Harrison (closest two) are two trails frequently visited by me, and have been about 4-5 other trails around the state too as well as the Silver Lake Sand Dunes about 2 dozen times this year.

Sounds like you're having fun with that set of toys! I sometimes miss those days but my back doesn't lol. You might want to hook up with the michigan atv group, I don't remember their exact name but they often have coordinated rides throughout the state with several being in my area, rose city, west branch, st helen... not too far from you. Great group of guys who are strong in their fight for atv rights as well. Good luck.

Leota Trail head in Harrison and the denton loop in south Houghton lake area is nice. You can camp along the river at the canoe camps and access both trail systems.
There is also Michigan Moto Mania Off Road Park in Harrison that is set up for ATV's and Bikes
